David Tredinnick: Speaking as a former Grenadier Guard who served in Northern Ireland, may I ask the Secretary of State to express his condolences to the families of the three Guardsmen and two military policemen killed yesterday in Helmand province? Does the Secretary of State recognise the contribution to the peace process made by the regiment of the Grenadiers in Northern Ireland, including through the building of the peace line? Finally, will he tell the House whether the upsurge in violence is due to new terrorist activity, or to the Provisional IRA under another name?
